Image sensor and electronic device including the image sensor

Abstract

An image sensor includes a sensor substrate including a first pixel group including a plurality of consecutively arranged first pixels, a second pixel group including a plurality of consecutively arranged second pixels, a third pixel group including a plurality of consecutively arranged third pixels, and a fourth pixel group including a plurality of consecutively arranged fourth pixels, and a nano-optical lens array including a first pixel-corresponding region facing the first pixel group, a second pixel-corresponding region facing the second pixel group, a third pixel-corresponding region facing the third pixel group, and a fourth pixel-corresponding region facing the fourth pixel group. The nano-optical lens array includes a plurality of nanoposts, and separates incident light according to wavelengths, multi-focuses green light on the plurality of first pixels and the plurality of fourth pixels, single-focuses blue light on the second pixel group, and single-focuses red light on the third pixel group.
